Question

Identify the graph that correctly represents the inequality |x + 1| + 2 >  5.

Answer 1

Answer: D. The last graph

Step-by-step explanation:

Answer 2

$|x+1|\ \textgreater \ 3$

The greater than 3 means that the graph will have a shaded region for when the absolute value of (x+1) is greater than 3.

The absolute value means that we are interested in the magnitude of x+1. That means that the the graph will be shaded where x+1 > 3, and where -x-1 > 3

If we solve both of these for x, we get:

x > 2 and x < -4

So the graph will look like the attached picture. Notice that the vertical lines are dotted rather than solid. This means that we are dealing with a greater than sign, not a greater than or equal to.
